Mechanical Waves

Front

What is a mechanical wave?

Back

A mechanical wave is a type of wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is wavelength?

Back

Wavelength is the distance between two corresponding points on consecutive waves, such as crest to crest or trough to trough.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is amplitude?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, indicating the energy of the wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How do sound waves travel?

Back

Sound waves travel through the vibration of particles in a medium, such as air, water, or solids.

Front

Why can't sound travel in space?

Back

Sound cannot travel in space because there is no matter (medium) for the sound waves to vibrate through.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation, such as sound waves.
